Possible faults

Although Briggs & Stratton brand engines have a good reputation, there are situations that can cause problems. The most common problem that any lawn mower owner may encounter is a situation where the engine does not start. The reasons for this problem may be:

• low quality fuel;
• incorrect operation of the air damper;
• The spark plug wire is not making contact.

If these shortcomings are eliminated, the operation of the garden device should improve immediately.

If the device begins to stall during operation, then you should pay attention to the quality and quantity of oil, as well as the battery charge. If smoke is coming from the mower, you need to make sure that the air filter does not have dirt on its surface (if necessary, clean it)

In addition, there may be excess oil inside.

Vibration of the garden machine may be due to the fact that the reliability of the bolt fasteners has been compromised, the knee shaft has bent, or the knives have been damaged. Unauthorized shutdown of the device can be caused by insufficient fuel level or lack of proper ventilation.

In addition, problems may arise in the operation of the carburetor or muffler. Failures can also occur if there is no spark.

In any case, it is important to entrust the repair of the device to professionals

In the next video you will see how to clean the carburetor on a Briggs & Stratton lawn mower.

Briggs & Stratton engines

One of the famous American Corporations for the production of internal combustion engines - Briggs & Stratton is located in the state of Wisconsin, with headquarters in Milwaukee, USA: - production of 4-stroke air-cooled gasoline engines in the power range from 3 to 25 Horse power. The produced engines are used to drive small-scale mechanization equipment. The engines are successfully used in lawn mowers and cultivators, walk-behind tractors and mini tractors, power plants and pumps; they are widely used in construction and special equipment. Today, the corporation's annual turnover is more than 1.5 billion US dollars. This amounts to more than 10 million engines of various modifications produced in the United States and Japan, and spare parts for them. To provide a sufficiently high level of service and repair, Briggs & Stratton has created a network of authorized service dealers from more than 30 thousand independent companies around the globe. The corporation employs more than 7,800 people. Their high professional training allows Briggs & Stratton to occupy high positions for many years in constant competition. The Briggs & Stratton engine models produced can be classified as follows: - Consumer: B&S Classic, B&S Sprint, B&S Quattro. — Improved consumer: B&S Quantum, B&S Intek, B&S Intek I/C. — Semi-professional: B&S Intek I/C, B&S Intek PRO. — Professional: B&S Intek PRO, B&S Vanguard. It must be taken into account that the higher the level in accordance with the above classification, then, accordingly, the capabilities of the engine increase and the reliability and operation with long-term daily operation are higher, but their cost is also higher. For comparison and understanding of engine serviceability, Briggs & Stratton provides MTBF ratings. According to the technical characteristics of the engines: - the “consumer” series works without requiring repairs, on average 500 hours, - “professional” - 3000-3500 hours. In order for the declared reliability and durability of engines, as well as the possibility of warranty service, to be fulfilled in real conditions, it is necessary to select an engine for a specific task. A sufficient advantage of engines manufactured by Briggs & Stratton is not only reliability and long service life, but also high performance characteristics, but also a wide level of service support, which in turn makes it possible to easily find repair service or spare parts and accessories. Gasoline generators GenPower

are equipped exclusively with proven B&S Intek PRO and B&S Vanguard professional series engines. Vanguard series is a single-cylinder engine with power from 4 to 13 horsepower. Engines of this series are assembled in Japan and are considered the most reliable and durable, both in comparison with the entire Briggs & Stratton model range, and among models of other similar manufacturing companies - their service life is 3000-5000 hours. The engines use overhead valves (OHV) of the Vanguard brand (assembled by Mitsubishi, Japan) from Briggs & Stratton. They are equipped with an automatic stop system if the oil level drops, have a high safety margin and are considered one of the most reliable in their class. The engines are designed for long-term operation (about 8 hours daily). The main applications are electrical units, rammers, seam cutters, walk-behind tractors, go-karts, compressors. GenPower generator sets use single-cylinder Briggs & Stratton Vanguard™ Commercial Power engines. All engines are four-stroke, 3000-3500 rpm. They are air cooled. Engine type OHV (overhead-valve) - overhead valve arrangement. Overhead valve engine, lined with oil pressure indicator. In its standard configuration, the engine has a fuel tank with a settling valve, a muffler and is mounted on powerful ball bearings, and it has a reinforced camshaft. The ignition coil has a “lifetime warranty”!!!

Typical faults and their elimination

Some typical faults can be easily fixed:

• If the starter cable pulls with force, the mower is most likely clogged with grass. It will need cleaning. Another cause of the malfunction is the engaged engine flywheel brake.
• If the engine does not start, the reason may be a faulty spark plug (it should be replaced), a dirty air filter (needs cleaning or replacement), or a clogged fuel filter (needs replacement).
• The same faults can cause a loss of unit power. In this case, you should additionally check the cutting height of the grass and, if necessary, reduce it. You should also check the carburetor adjustment.
• The grass is not cut, but stretches - a sign of dullness, breakage or bending of the knives (cutting disc). Knives need to be sharpened or replaced.
• The appearance of dark smoke, as a rule, does not mean anything dangerous - either too much oil has been poured in, or it has got on the hot parts of the device and will simply burn out after a while. But if the smoke is light, it may indicate a serious problem and you should contact a professional.

Operating instructions, maintenance of lawn mowers

Rules for engine maintenance using the example of the operating manual for a lawn mower with a Briggs and Stratton 500 series 158 cc engine:

• daily or every 5 hours - clean the grille that protects against debris, clean the safety shield;
• every 25 hours of operation - maintenance, cleaning the air filter;
• every 50 hours or once a season - you need to change the oil, check the condition of the spark arrester;
• every 100 hours or once a season - servicing the air filter cartridge, cleaning the cooling system, changing the oil in the gearbox;
• Once every 100-300 hours it is necessary to clean the combustion chamber from carbon deposits.

Oil and fuel

Oil for a Briggs Stratton lawn mower, according to the manufacturer’s recommendation, must be chosen in a strictly defined category. For example, the quality class must be at least SF; a class higher than SJ is allowed. There is no need to use oil additives. The oil viscosity should be at SAE30 level if the air temperature at which the lawn mower is operated is plus 5 and above.

At air temperatures from minus 18 degrees Celsius to plus 38 degrees, use 10W30 oil for lawn mowers; it gives easy starting, but increases the risk of engine overheating if the air temperature crosses +28 degrees.

Gasoline for a mower with a Briggs and Stratton engine should only be of good quality. The ideal choice would be unleaded gasoline with a minimum octane number (87/87 AKI (91 RON). Do not use cheap gasoline such as E85. Do not mix different types of fuel. The shelf life of the lawn mower with gasoline in the gas tank should not exceed 24 months.

Briggs & Stratton I/C Engine Features

• Low Fuel Consumption: Overhead valve technology and an advanced combustion chamber provide exceptional fuel efficiency and consistent power.
• Environmentally friendly: ICEs meet the most stringent emission standards.
• Advanced overhead valve (OHV) technology improves intake and exhaust flow and combustion efficiency, resulting in increased power and lower fuel consumption.
• A cast iron bushing, forged crankshaft and dual ball bearings improve engine strength and make it more reliable and durable.
• This lightweight, high-flow air cleaner provides powerful filtration and protects engine parts from premature wear.

Oil selection

Manufacturers of Briggs & Stratton brand engines recommend that users use a strictly specific type of oil. Its category must be at least SF, but a class higher than SJ is also allowed. There is no need to use any additives. The oil change should be carried out strictly according to the instructions that come with the device.

If the ambient temperature in the area where the grass mower is operated is in the range from -18 to +38 degrees Celsius, then the manufacturer recommends using 10W30 oil. It will make it easy to start. At the same time, keep in mind that if you use this product, there is a risk of overheating the device. Either way, only high quality oil should be used.
